Abstract:
We have revised the Astro Space Center catalog of Class I methanol
masers detected in starforming regions (MMI/SFR), mainly at 44GHz,
and created a new electronic version of the catalog. Currently, the
catalog contains 206 objects, selected from publications through 2011
inclusive. The data from the survey of Chen et al. (2011, Cat.
J/ApJS/196/9), performed specifically for objects EGO, which form a
new specific catalog, are not included. The MMI/SFR objects were
identified with emission and absorption objects in the near IR,
detected during the MSX and Spitzer space missions. Seventy-one
percent of Class I methanol masers that emit at 44GHz and fall within
the Galactic longitude range surveyed by Spitzer (GLIMPSE) are
identified with Spitzer Dark Clouds (SDCs), and 42% with Extended
Green Objects (EGOs). It is possible that Class I methanol masers
arise in isolated, self-gravitating clumps, such as SDCs, at certain
stages of their evolution. A sample of SDCs is proposed as a new
target list for Class I methanol maser searches. A detailed
statistical analysis was carried out, taking into account the
characteristics of the regions of MMI/SFR formation presented in the
catalog.
